Abstract:
Objective
To analyze the features of ultrasound, X-ray and CT in the diagnosis of acute osteomyelitis in children, and to summarize the diagnosis experience.
Methods
A total of 28 children with acute osteomyelitis treated in Shenyang Children's Hospital from February 2012 to August 2015 were selected as the research subjects, and all of them were diagnosed by ultrasound, X-ray and CT.
Results
The number of bone change detected by CT was higher than that by X-ray and ultrasound. A total of 37 items of round bone destruction and special bone destruction were detected by CT, while 15 by X-ray and 20 by ultrasound. Eleven items of periosteal proliferation was found by CT, and 6 by X-ray and none by ultrasound. The rate of CT in detecting special bone destruction was higher than that of ultrasound and X-ray. The rate of CT in detecting remnant expansion bone shell destruction was higher than that of X-ray. The rate of CT in detecting periosteal proliferation, periosteal change and cortex change was higher than that of ultrasound. The rate of X-ray in detecting periosteal and cortex change was higher than that of ultrasound. All the differences were of statistical significance(P<0.05).
Conclusion
In different time periods, the changes of the disease were influenced by the changes of ultrasound, X-ray and CT on the soft tissue and the changes of the periosteum and cortex. Ultrasound, X-ray and CT can be used in the diagnosis of acute osteomyelitis in children, and CT gives more information.
